Why this Research?
Contribution of DON to nutrient
enrichment and eutrophication in
water bodies is poorly understood
and usually neglected.
Objective:
To determine the longitudinal
evolution of DON and it’s
bioavailability from freshwater to
estuarine ecosystem.
Bioassay Experiment:
Five days incubation under 12:12
light:dark cycle.
Outcome of Research?
Free flowing river
(1‐5)
Impounded river
(6&7)
Estuarine
(8‐11)
